Could you provide example code to integrate the API?

You can use general logic. Get request and JSON parsing:

import requests

url = 'https://cryptonews-api.com/api/v1'

params = dict(
    tickers='BTC,ETH,SHIB',
    items=50,
    token='YOUR_TOKEN',
)

resp = requests.get(url=url, params=params)
data = resp.json() # Data from API

or less code

import requests

url = 'https://cryptonews-api.com/api/v1?tickers=BTC,ETH,SHIB&items=50&token=YOUR_TOKEN'

resp = requests.get(url=url)
data = resp.json() # Data from API
